Thanks, Alan. I noted in the launchpad bug that you updated this one.

The value `set-from-style' is the uninitialised "global" value that
CC Mode gives certain variables ("style variables"). That a buffer's
copy of a variable still contains that value implies that nxhtml-mode has
failed to initialise CC Mode properly.

I've downloaded that and grepped it. There are no CC Mode initialisation
calls in php-mode.el. For comparison, there are three such calls in
csharp-mode.el, namely:
(c-initialize-cc-mode t)
(c-init-language-vars csharp-mode)
(c-common-init 'csharp-mode)
C#'s initialisation is probably correct, and could serve as a model for
PHP Mode. In particular the call to `c-common-init' is the essential
one.
I don't have an account on Launchpad, and I really don't want to "read
the guide" or "take a tour" (I've got bugs to fix ;-), so I won't be
contributing to the bug's progress on Launchpad. If nxhtml-mode's
maintainer wants to contact me, I'd be happy for him/her to email me
personally or on the CC Mode mailing list at bug-cc-mode@gnu.org.
Thanks once again for taking the trouble to submit such a clear bug
report.
